Our fund includes a portfolio of over 15 companies that form the foundation behind the Notes.

As mentioned have an attorney or title company draft the note and mortgage.

We are considering becoming a private lender with them and I am doing some background research on him and his companies and wondering if anyone has done any deals with them.

This is a very labor intensive process for most big box skip trace companies because it cannot be automated.

A professional trustee such as Exeter Trust Company is the way to go if you want it done right, imo. 

The only logical way a company would know their average tenant stay, is by running a report.

If you don't plan on paying cash and have to leverage with an owner-occupied loan product then you should set up your LLC as a property management company because you will not be able to borrow in the name of the LLC.  

I'm not trying to be a jerk but truly trying to understand where this cash flow is coming from buying in 2023-2024, although I can understand with Columbus I could see it appreciating with those companies moving there.

Is there an energy company (electrical and Gas) that will do roll overs?

The specialist I recommend you have is an attorney to properly draft the documents and a title company to facilitate the deal.
